The italicised sections are ones I think we can discount; the rest I think is in someway still in play. Best read from bottom to top I think:
1911 Census

With Father in law, Timothy Lea, 50 (scribbled out and re-written), Lab Iron works, b. Ireland
I think we can discount as Mary’s maiden name is Conner (see 1866 marriage record below), but doesn’t account for father-in-law being Timothy Lea (loose end)
